Build/Fix A Website

Hi there, I run a Wordpress website that sells tickets to events (parties), and I need a number of things set up/fixed. I am hoping to hire someone who can do ongoing work on the site - perhaps we can negotiate an hourly or ongoing rate once the below are completed. -Currently I am using Event Tickets Plus ([login to view URL]), and for some reason customers are being sent triplicate tickets (I can view the emails sent via Postmark). Please investigate and fix (urgent). -Woocommerce Sales need to be reassigned to another Vendor -Need to set up Paypal Adaptive payments so sales go to vendor, and booking fees go to me. -Need to fix Facebook login so that it pulls user information from site (so user doesn't have to type in information), as well as date of birth and gender. You may be able to find another suitable plugin for this. -Set up Google+ and Paypal login/registration. -Pull Paypal billing information (eg address) to site -Make Ticket (Woocommerce Product) disappear once out of stock -Assist me to implement my conditional count down timer (disappears once event tickets go on sale) -Set up for Google Analytics Experiments (eg, A/B test between a buy now/book now button, website colours, etc) You will be working on a staging site, and then advising me how to implement onto the live site.
